fuel cut @ 13psi?

I hooked up my MBC,and boost gauge, and even with the knob all the way in I can't get over 13psi. I have hooked it up two different ways, input from the turbo nipple, and from the BOV. I am also getting fuel cut, and a CEL. I have found no boost or vacuum leaks.

What is the CEL......Did you have it scanned? I don't see how you are getting fuel cut with the T-25. See what the CEL is and let us know.

I don't have a scanner, It will be a few days before I can get to the shop. I will let you know then.

I was looking for vacuum leaks, and noticed that my EGR solinoid is busted. Do you think this could be part of the problem? It has some nasty backfires.

:iceslolan Good news for me, it was not fuel cut. I found the egr solenoid to be busted where the vacuum line attaches, so instead of buying a new one I just made a block off plate. Problem fixed no more backfire or bucking. I didn't even get a CEL, though I thought I should have.

:eek7: Stupid me, I crossed the vacuum lines to the mbc. I had the input on the output and the output on the input. I just made a couple of runs, and got the boost up to 16psi, with only 1 or 2psi spike.
